Fall 2020 - I really appreciated how she became more and more accommodating to people's circumstances and learning pace as the quarter progressed. She turned the weekly quizzes into SYOP where you present your own problem and solve it yourself, and is 0% or 100% only based on effort you put. You can just grab a question from the textbook (that isn't answered in the textbook) and solve it yourself, or talk about any new concept you learned or had difficulty grasping in the class. After the first midterm, she also gave extra 0.5% credit for each Zoom lecture you attend for a total addition of 5% extra credit. She really tried her best to explain the lectures clearly and you could really tell, but sometimes things can get really hard to understand especially when there is so much content to cover in 10 weeks. Sometimes, homework or test questions wouldn't even be like what was explained in class, and would have you take the extra mile to understand the lesson which I thought at first was unfair, but I guess it was cushioned by all the opportunities for leniency in other places. Overall, I enjoyed my quarter with Nina, and she is extremely friendly in Office Hours too!
Spring 2020 - I feel like I learned a lot in this class. In this class 50% of the grade was a group project (which included a 30 minute presentation and a PNAS style 6 page paper). Dr. Otter was a really good lecturer, and she was really willing to meet with us and help us with ideas for the project, and even look at drafts for the final paper. She genuinely cared a lot about student learning. The material taught in class was not too difficult, and the project was a lot of work - but it was totally worth it, and was a great learning opportunity. Also, the only listed prereq is Math 115A, but I would highly recommend a probability class like 170A/E and a class in differential equations like 33B or 134.
